There were multiple issues involved. Biggest of all, it required a patch to
QEMU that wasn't maintained and wasn't upstream (i.e. vanilla QEMU didn't work
with DPDK's implementation of IVSHMEM support). Second, it was basically hacked
in to EAL in order to support what it does , and the engineering effort to
fix all of that isn't worth the benefit it would provide, as no one appeared to
be using it heavily enough to object to its deprecation.
Hope this clears things up.
